Excellent durability for daily wear
Color: Gold Paperclip
I bought these earrings a year ago and I've been wearing them ever since! I never take them off because they are so comfortable. They never come unlatched and they are very durable. They look great and I love how they have some movement because of the two loops hooked together. For me the size is perfect, but you can always remove the dangling hoop to decrease the weight and create a smaller look. Even with booth hoops installed, they are so light that I cannot feel them in my ears. They would make a lovely gift because they look more expensive than the price I paid.

Good quality
Lovely earrings. A little smaller than I expected but
Going to keep them. A reasonable purchase. Lightweight and clasp a little tight but better than loose.

Cute but small
Color: Gold Paperclip
These are cute but they are smaller than I thought they would be. The only thing I did not like was that they kept coming apart. The two links would unhook and one hook would fall off. I squeezed them a little tighter and that helped.
